In today's digital age, security is a top priority. One of the best ways to enhance security is by using random passwords for your accounts. While Safari and password managers offer convenient ways to generate random passwords, there might be situations where these options aren't available. In this article, we will explore various methods to create random passwords on your Mac without using Safari. We will dive into using Keychain Access, Terminal commands, and even Automator to accomplish this task. So, let's get started and learn how to enhance your online security with random passwords.

Why Use Random Passwords?

Before delving into the different methods of generating random passwords, it's essential to understand why random passwords are crucial for online security. Random passwords are more secure than passwords that are easily guessable, such as names, birthdays, or commonly used words. By using random passwords, you decrease the likelihood of someone guessing or hacking into your accounts. Random passwords are typically a combination of uppercase and lowercase letters, numbers, and special characters, making them more complex and harder to crack.

Using Keychain Access

One way to generate random passwords on your Mac is by utilizing an app called Keychain Access. Although this app is primarily used for managing passwords in Safari, we can leverage its functionality to create new passwords. To access Keychain Access, you can use Spotlight and search for it. Once open, go to File and select "New Password Item." This will bring up the Password Assistant, which allows you to generate random passwords. You can customize the password type, length, and whether it includes letters, numbers, or both. Once you have your desired password, you can either copy and paste it or manually enter it into the application or website you are creating a password for. Remember to save the password securely using a password manager or another safe method.

Generating Random Passwords with Terminal Commands

If you prefer using Terminal and command-line tools, there are several commands you can use to generate random passwords quickly.

Simple Terminal Command

The simplest command involves generating a random password using the current date and time. By using a checksum app, we can create a sequence of random numbers and letters based on the current timestamp. This command can be repeated to generate multiple passwords or tweaked to extract a specific number of characters. However, keep in mind that this method may not provide the same level of complexity as the other options.

Using OpenSSL

Another method involves using the OpenSSL app within Terminal. By calling the "random" function in OpenSSL, we can generate a random base64 number, which includes upper and lowercase letters and numbers. This method provides a higher level of complexity and is suitable for creating quick and secure passwords.

More Advanced Terminal Command

For those seeking more control and customization, a more advanced Terminal command can be used. This command utilizes the "urandom" binary file in the developer folder to generate a random number. The generated characters include lowercase and uppercase letters, numbers, and specific symbols. The command allows you to specify the length of the password and modify the character set to meet your requirements. Remember to copy and securely store the passwords generated using the Terminal.

Creating Random Passwords with Automator

If you prefer a more visually-oriented approach, you can utilize Automator, a built-in macOS app, to create a workflow that generates random passwords. By creating a Quick Action or an Application in Automator, you can use JavaScript to define the characters you want to include in the passwords and the desired length. The workflow will generate a password and copy it to the clipboard, allowing you to paste it wherever needed. This method provides a user-friendly way to create random passwords without the need for extensive Terminal commands.


Enhancing your online security is vital in today's digital landscape, and using random passwords is a fundamental aspect of achieving that goal. In this article, we explored various methods of generating random passwords on your Mac. From using Keychain Access to Terminal commands and Automator workflows, you now have a toolkit of options to create secure passwords in any situation. Remember to store and manage your passwords securely using a reputable password manager. Stay safe, and protect your online accounts with random, complex passwords.
